Sheep, protein, degradation, performanceAbstract
A feeding trial was conducted with sheep fed rations containing 40,0, 50.0 and 60.0% degradable protein. Feed consumption, daily weight gain and feed conversion were determined with twelve criollo castrated males with an average initial weigth of 19.8 kg. The sheep were randomly assigned to treatments and placed in individual pens where they were supplied the experimental rations and clean water twice a day. Feed consumption was not different (P>0.05) among treatments and were 0.933, 0.916 and 0.843 kg for the animals receiving rations containing 40.0, 50.0 and 60.0% degradable protein, respectively. Daily weigth gain and feed conversion of animals receiving rations containing 40.0 and 50.0 % degradable protein were not different (P>0.05) and were better (P<0.05) than those shown by the animals receiving the ration containing 60.0% degradable protein. Daily weight gains were 0.166, 0.165 and 0.081 kg and feed conversions were 5.67, 5.62 and 10.81, for sheep receiving rations containing 40.0, 50.0 and 60% degradable protein, respectively. Sheep fed rations with lower protein degradability had better performance than those fed rations with higher protein degradability.
